Itraxel 100 Capsule contains Itraconazole 100 mg, a broad-spectrum triazole antifungal agent indicated for the treatment of various systemic and superficial fungal infections. Itraconazole exerts its antifungal effect by inhibiting the cytochrome P450-dependent enzyme lanosterol 14-α-demethylase, which is essential for the conversion of lanosterol to ergosterol, a critical component of fungal cell membranes. Disruption of ergosterol synthesis results in increased membrane permeability and ultimately fungal cell death. Itraxel 100 is effective against a wide range of pathogenic fungi including Candida species, Aspergillus species, and dermatophytes. It is commonly prescribed for conditions such as oropharyngeal and esophageal candidiasis, onychomycosis, blastomycosis, histoplasmosis, and aspergillosis. The oral capsule formulation ensures convenient administration with good bioavailability when taken with food. Dosage and duration of therapy should be tailored based on the severity and type of infection, patient response, and clinical guidelines. Caution is advised in patients with hepatic impairment, congestive heart failure, or those receiving concomitant medications metabolized via the cytochrome P450 system due to potential drug interactions. Monitoring liver function tests during prolonged therapy is recommended. Itraxel 100 Capsule should be used under medical supervision to ensure safety and efficacy.
